  • Taps on power bus?

    I have been using insulation displacement "suitcase" connectors (IDC) to tap the power bus lines (14 gauge) for the track feeders. But I've been having real problems installing the IDC, apparently the insulation on my wire is too tough and the metal bar that's supposed to part the insulation and connect the wires isn't making good/even contact.

    Does anyone have a suggestion/recommendation for alternatives? My track bus is already installed, and does not have enough slack in it to cut the bus in multiple places to add in taps that break the wire. So I'm stuck with something that can make a T connection into the bus wires.

    Thanks in advance!

    Cut the bus and strip; Twist each end with feeder and attach a wire nut.

      I've cut the insulation off a short segment in the middle of a wire and soldered/taped. But one thing about a buss, if it isn't nailed to the framework too vigorously, you can just start cutting and wire-nutting, and when you get to the end and it doesn't go far enough, splice a foot or two of new wire in.

        I have a wire stripper that cuts the insulation then spreads it a quarter to half an inch and allows me to attach a wire and solder it. Harbor Freight and other sell similar devices. It works well for me on my power buss.

        Here is a short video of a Klein cutter, mine from Harbor Frt is orange and works on the same principle. Not sure on the adjustable extras, HF didn't 'splain that part....The second part he shows is what I use for my layout dcc buss.

          Karl,

          I think I have one of those tools you describe. It does just what you say, cuts the insulation and spreads it away from the cut to allow soldering. Although the tool is actually meant to strip the insulation from the end of a wire, It works just as well making a naked wire in the middle to allow soldering.

          BTW, Where's the video of the Klein cutter?

              I go with the wire stripper all the time. Offset the soldering spots.

              WORKS LIKE A CHARM!

                Thanks for the thoughts. Soldering the existing bus is just not feasible, there would be too much contortion and even lying on my back. If I have to go that route, I'll rip out the bus and redo the whole thing from scratch.

                But I forgot I had a tool to crimp the suitcase connectors, maybe that'll give me better luck. (Getting old and forgetting things sucks, it's been well over a year since I touched wiring.)

                  I -forgot- I bought a tool to crimp suitcase connectors! Once I found that, my problems installing the IDCs went away. https://www.amazon.com/ScotchLok-Con.../dp/B000JCRW0A

                    deemery: I'm so old that I forgot that I was old!!!

                    I like using the IDC's and I use a channel locks to close the IDC's. Using the IDC's sure beats soldering for older modelers.
